WILLIAM FUZZARD, OF CHELSEA, MASSACHUSETTS.

IMPROVEMENT IN STEAM-TRAPS.

Specification forming part of Letters Patent No. 55,081, dated May 29, 1866.

To all whom 'it may concern:

Be it known that I, WILLIAM FUZZARD, of Chelsea, in the county of Suffolk and State of Massachusetts, have invented a new and Improved Steam-Trap; and l do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l represents a longitudinal central Fig. 2 is a similar section ot a moditication thereof'.

Similar letters of reference indicate like parts.

This invention consists in the arrangement of a buoyant stopper, made ot' cork or other material of less specitic gravity than Water, and placed in the exhaust-chamber, which is provided with a suitable seat-at its bottom in such a manner that Whenisteam passes into -tlie exhaust-chamber the buoyant stopper is depressed on its seat by its own gravity, assisted by the pressure otl the steam; but it water accumulates in the exhaust-chamber, the buoyant stopper begins to float and the 'Water has a chance to escape.

A represents the exhaust-chamber of a steam-coil or other device, which is heated by. steam, and which is to be provided with a suitable steam-trap. This chamber is lnade of brass, iron, or other suitable material, and it is provided at its bottom with a Hat or con-4 other suitable material lighter than water,

and it is placed loosely into the chamberA, so that the same, when the chamber is empty or tilled with steam, will sink down on its seat and close the discharge-opening a.

It' water accumulates in the chamber A, the buoyant stopper floats oft' from the dischargeopening and the Water has achance to escape.

By this arrangement the waste ot' steam can be eft'ectually prevented and a steam-coil can be heated with the lgreatest possible economy.

The trap is very simple in its construction, it can be easily connected to a steam-coil of any desired construction, and it is notI liable to get out ot' order.

What I claim as new, and desire to secure by Letters Patent, is

The buoyant stopper C, in combination with the exhaust-chamber A and a suitable seat, B,- in said chamber, substantially as and for the purpose described.

WILLIAM FUZZARD.
